NCT07869121

Brief Summary

The proposed study addresses this gap by prospectively evaluating patient-reported outcomes, imaging endpoints, and safety through 12 months after BCI-augmented repair in IAT and MSR patients. The purpose is to evaluate clinical outcomes (effectiveness) following the use of REGENETEN to augment Achilles tendon surgical procedures.

  • Achilles Tendon Total Rupture Score (ATRS)

    preop/screening, 6 week postoperative , 3 months postoperative, 6 months postoperative, and 12 months postoperative

  • Victorian Institute of Sport Assessment Achilles (VISA-A)

    6 weeks postoperative , 3 months postoperative, 6 months postoperative, and 12 months postoperative

  • +2 more secondary outcomes

Other Outcomes (3)

    preoperative/screening, 3 months postoperative, 6 months postoperative, and 12 months postoperative

  • Range of Motion (ROM)

    preoperative/screening, 3 months, 6 months, and 12 months postoperative

  • Charlotte Hindfoot Assessment

    preoperative/screening, 6 weeks postoperative, 3 months postoperative, 6 months postoperative, and 12 months postoperative

Study Arms (2)

Krakow sutured, bundle-to-bundle repair

Krakow sutured, bundle-to-bundle repair for mid-substance primary Achilles rupture with REGENETEN augmentation. Fixation of REGENETEN implant to be completed with tendon anchors.

Device: REGENETEN

Achilles tendon reconstruction

Achilles tendon reconstruction, with or without concomitant calcaneoplasty/bursectomy for insertional Achilles tendinopathy. Fixation of REGENETEN implant to be completed with tendon anchors.

Device: REGENETEN

Interventions

REGENETENDEVICE

The REGENETEN Bioinductive Implant is a scaffold made from highly purified type I collagen fibers. Following fixation, using its efficient and suture-free technique, the REGENETEN Implant is resorbed and replaced by a new layer of tendon-like tissue within 6 months increasing tendon thickness, and creating an environment conducive to healing.
